Pantaleon was a very short-lived ruler, judging by the sxtreme scarcity of his coins. He is dated to c. 185-180 BCE. Conventionally, his coins are presented after
those of Agathocles, but, considering that Agathocles issued coins in commemoration of Pantaleon, it seems more logical to me to present the coins of Pantaleon first.

The first Greek coin aimed at an Indian audience! We have an Indian style deity, a square flan (recall that Mauryan coins were
typically.square), a legend in Brahmi, and a weight-standard that seems to be associated with an Indian standard.
